Improvement of Power Quality using Dual Control Strategy of Unified Power Quality Conditioner (UPQC)

  Mr. Mayur P. Baseriya,  Mr. K N. Sawalakhe

This paper presents an ideal and effective control strategy to compensate harmonics and the load-reactive power demand by connecting a three-phase unified power quality conditioner (UPQC). In order to reduce the power quality problems this paper presents, the flexible control technique for UPQC as dual control in power distribution system. The polluted loads at the end user side are always creates the power quality problems. In this paper, UPQC system is used for series and parallel power conditioning and they act as sinusoidal current and voltage source inverters respectively. The series and shunt active power filter (APF) injects voltage and current at significant phase angle which converts non-sinusoidal electrical quantities into sinusoidal electrical quantities. This is also called as dual compensation. The proposed UPQC system can be connect to both three-phase three-wire and three-phase four-wire distribution systems. The UPQC system can enhance the power quality in distribution system at the point of common coupling (PCC) under non-ideal mains voltage and unbalanced load conditions. The simulation results based on MATLAB/Simulink are analyzed and studied.
